Methyl glycosides are identified as glycosyl donors for the synthesis of glycosides, disaccharides and oligosaccharides

Abstract

Stable methyl glycosides are identified as glycosyl donors in the presence of AuBr₃ in acetonitrile; a panel of aglycones comprising aliphatic, alicyclic, steroidal and sugar alcohols are examined successfully for the glycosylation reaction and methyl glycosides of di- and tri- saccharides are converted to corresponding tri- and tetra-saccharides exploiting salient features of our novel activation protocol.
